摘　　要：辽宁中部供水工程从大伙房水库取水供水至辽宁省中部抚顺、沈阳、辽阳、鞍山、营口、盘锦6市,该工程距离长、多分支、流量大并且为密闭供水,线路中设置1座鞍山加压站,泵站为接续式加压布置形式。本文运用bentley hammer软件对该工程建立模型,通过对比该泵站设置旁通管与不设置旁通管两种工况,对其进行停泵水锤计算,分析对比该类接续式泵站设置旁通管后在水锤防护中的作用。Central Liaoning Water Supply Project draws water from the Dahuofang Reservoir and supplies it to six cities in central Liaoning Province,Fushun,Shenyang,Liaoyang,Anshan,Yingkou,and Panjin.This project features a long distance,multiple branches,high flow rate,and a closed water supply system.Along the route,there is one booster station in Anshan,where the pumping station adopts a relay boosting mode.This paper utilizes Bentley Hammer software to model the project and compares two operating conditions:one with a bypass pipe installed at the pumping station and one without.By conducting pumping-off water hammer calculations,the study analyzes and compares the role of bypass pipes in water hammer protection for such relay pumping stations.
